Why are people between the ages of 16 and 30 so stupid?

I'm stupid, you're stupid, we're all stupid! :)

Just because you see people posting stupid questions doesn't mean the age range of 16-30 year olds are stupid. Everyone is different and everyone has their own traits, You just have to learn to look past the immature ones and move on.. Don't just judge a book by its cover. There are actually some good intelligent ones in those age range.

Jeez someone is going through a bitter frustration point in their life. Most of these are troll posts (joke posts) and those kinds of question belong to the 20-30 demographic while even more stupid questions and insecure/scandalous questions belong to the 13-20 group. Yahoo answers is just getting raided with little trolls.

Physiological, people's brains don't develop until they hit 30 or so. The thing about Yahoo Answers is that some of the answers cannot be taken seriously. The website encourages you to ask questions ad a way if getting involved.
